Shipping issues & replacements

If it arrived broken,we'll fix it.

Our policy is narrow on purpose. Once a vial leaves our chain of custody we can't verify how it was stored, handled, or transported — so we don't accept returns into stock. We do cover anything that goes wrong on the way to your bench.

What we cover

FREE / REPLACEMENT

Damaged on arrival

Broken vial, compromised lyophilized cake, or visibly damaged packaging. Email photos within 48 hours of delivery and we'll ship a free replacement.

FREE / REPLACEMENT

Lost in transit

Carrier scan stalls, package marked delivered but never arrives, or stuck in a depot for more than 7 business days. We'll work with the carrier and ship a replacement at no charge.

FREE / REPLACEMENT

Wrong item shipped

We packed the wrong compound or the wrong dose. Reply with photos and we'll send the correct vial out the same business day.
